@ai6yr I have to share this. I was the lead on the PR team that helped launch this product back in 1996.

I LOVED this promo mug because a wave form showed up when you poured hot water in it, showing what people were missing with other 'scopes.

It was the hottest giveaway & I credit the marketing people at Tektronix for the idea & execution. I've kept in on my desk for 30 years! #Oscilloscope

Wow, this tune is sick! ✋😎🤚🪩

Added some oscilloscope measured waveforms to my blogpost about the hc-sr04 ultrasonic distance sensor. Trigger pulse width was off from the expected width on linux. Ultrasonic pulses clearly visual as well

A while back I got a new digital 'scope. The one I'd been using was okay, but only 8-bit and had some other limitations. The vertical resolution was actually starting to make it difficult to get accurate-enough readings of some things I was working with.

The new one is 12-bit. That is likely to be better than I will ever need. I'm happy with it. Being several years newer (and a different brand) it brings some new #features to the table.

One is that you can use it as a digital logic analyzer - it can sample a whole lot of inputs (rather than just 4 analog channels) quickly if it only has to tell on from off. But you have to get a whole lot of #signals into the #scope before you can do that, so you need a #connector with a lot of pins/signals.

You could use something standard for this type of application (which is still going to be a limited-audience part), or a custom thing, but those options are expensive. So instead, if you're the manufacturer, you find a common (and therefore #cheap) #connector with lots of #pins, and you re-use that. Done and dusted!

They picked ... the HDMI connector. It's there at the bottom of the middle of the control panel. And in the manual is the prominent (not) warning:

> WARNING: Non-standard HDMI interface, Siglent device ONLY, or you will damage your device.

Yes, if you plug anything HDMI-related into this obvious #HDMI port, you will cause damage to your 'scope, or your other device.
